“…In general, structures that had been initiated before the treatment became enlarged more than those of the comparable controls. The increased growth in height is a characteristic response of gibberellic acid treatment (Brian, 1958) and was previously reported for normal tomatoes (Rappaport, 1957;Kiermayer, 1960). In the present investigation, however, lanceolate showed a greater response than normal, but both in normal and in lanceolate, there were more as well as longer internodes produced during the same time interval.…”

“…Consistently, disruption of GA biosynthesis in tomato by gib1 , gib2 and gib3 mutations results in dwarfism and failed fruit set and development, while application of GA to these mutants rescues these defects, indicating that GA is essential for the development of the whole plant, and also for fruit set (Bensen and Zeevaart 1990). On the other hand, GA application does not increase final fruit size (Gustafson 1960, Rappaport 1957). Additionally, GA induction is stimulated by auxin, suggesting that GA biosynthesis is coordinately regulated by auxin.…”

Genes that influence yield in tomato

Yield is the most important breeding trait of crops. For fruit-bearing plants such as Solanum lycopersicum (tomato), fruit formation directly affects yield. The final fruit size depends on the number and volume of cell layers in the pericarp of the fruit, which is determined by the degree of cell division and expansion in the fertilized ovaries. Thus, fruit yield in tomato is predominantly determined by the efficiency of fruit set and the final cell number and size of the fruits. Through domestication, tomato fruit yield has been markedly increased as a result of mutations associated with fruit size and genetic studies have identified the genes that influence the cell cycle, carpel number and fruit set. Additionally, several lines of evidence have demonstrated that plant hormones control fruit set and size through the delicate regulation of genes that trigger physiological responses associated with fruit expansion. In this review, we introduce the key genes involved in tomato breeding and describe how they affect the physiological processes that contribute to tomato yield.

“…High temperatures reduce fruit set and fruit production in tomato 9 , in eggplant 11 and also in bell pepper 2 . Plant growth regulators such as auxin and gibberellins are known to affect parthenocarpy 7 and fruiting 10 ; therefore, synthesized auxin and gibberelins are often used for promotion of fruit set in some fruit vegetable production including tomatoes. Though tomatoes are usually treated with synthetic auxin during cool and mild seasons in Japan, the rate of fruit set under high temperature conditions is still low.…”

The effects of plant growth regulators on fruit set of tomato (Lycopersicon esculentum Mill.) under high temperature were examined in a controlled environment and a field under rain shelter. Tomato plants exposed to high temperature (34/20ºC) had reduced fruit set. Treatments of plant growth regulators reduced the fruit set inhibition by high temperature to some extent, especially treatment with mixtures of 4-chlorophenoxyacetic acid (4-CPA) and gibberellins (GAs). In the field experiment, tomatoes treated with a mixture of 4-CPA and GAs showed increased fruit set and the numbers of normal fruits (excluding abnormal types such as puffy fruit) were more than the plants treated with 4-CPA alone during summer.
